OBJECTIVES: To retrospectively evaluate the feasibility of CT assessment-based direct surgical resection of part-solid nodules (PSNs) with solid components > 5 mm without preoperative percutaneous transthoracic needle biopsies (PTNBs).
METHODS: From January 2009-December 2014, 85 PSNs with solid components > 5 mm on CT were included. Preoperative PTNBs were performed for 41 PSNs (biopsy group) and CT assessment-based direct resections were performed for 44 PSNs (direct surgery group). Diagnostic accuracy and complication rates of the groups were compared.
RESULTS: Pathological results of 83 PSNs excluding two indeterminate nodules included 76 adenocarcinomas (91.6%), two adenocarcinomas in situ (2.4%) and five benign lesions (6.0%). In the biopsy group, the overall sensitivity, specificity and accuracy for the diagnosis of adenocarcinoma were 78.9% (30/38), 100% (1/1) and 79.5% (31/39), respectively. Pneumothorax and haemoptysis occurred in 11 procedures (26.8%). In the direct surgery group, the respective values for the diagnosis of adenocarcinoma were 100% (38/38), 0% (0/6) and 86.4% (38/44), respectively. Seven pneumothoraces (15.9%); no haemoptysis occurred during localization procedures. There were no significant differences in diagnostic accuracy (P = 0.559) between the two groups.
CONCLUSIONS: CT assessment-based direct resection can be reasonable for PSNs with solid part > 5 mm.
KEY POINTS: • 91.6% of PSNs with solid component > 5 mm were adenocarcinomas. • PTNBs for PSNs with solid component > 5 mm had 79.5% accuracy. • CT-based resection for PSNs with solid component > 5 mm had 86.4% accuracy. • CT-based resection without biopsy can be a reasonable option in routine practice.
